The ..config for my linux kernel
If I hibernate from the console, thaw, and switch between the console
and X, the gpu hangs itself. The machine becomes unresponsive except
for the power button.
21:12:16 kernel: [drm] GPU HANG: ecode 8:0:0x0f71ffff, in Xorg [2047],
reason: Hang on render ring, action: reset
21:12:16 kernel: [drm] GPU hangs can indicate a bug anywhere in the entire
gfx stack, including userspace.
21:12:16 kernel: [drm] Please file a _new_ bug report on
bugs.freedesktop.org against DRI -> DRM/Intel
21:12:16 kernel: [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
21:12:16 kernel: [drm] The gpu crash dump is required to analyze gpu
hangs, so please always attach it.
21:12:16 kernel: [drm] GPU crash dump saved to /sys/class/drm/card0/error
21:12:16 kernel: drm/i915: Resetting chip after gpu hang
I tried to bisect, and found
commit 068715b922a6f87c454cdfa15bb8049d2076eee6

drm/i915/cmdparser: Add the TIMESTAMP register for the other
engines
as the first bad commit, i.e with a gpu hang after hibernation. This
sseems spurious, reverting this commit didnt not help.
This is a Lenoveo T450s with Broadwell-U Integrated Graphics. I attach
my .config and /sys/class/drm/card0/error.
